National Weather Service observations for October 2, 2026, showed widespread precipitation concentrated across the Southeast, driven by a slow-moving cold front interacting with deep tropical moisture from the Gulf of Mexico. Key West recorded 3.5–5.5 inches of rain, setting daily records, while Miami-Dade and parts of Alabama, Georgia, and the Carolinas experienced repeated rounds of heavy showers and thunderstorms with locally elevated totals. NOAA and NWS model guidance highlighted high precipitable water values and frontal convergence as key drivers, producing 60–90% rain probabilities in southern zones versus lower chances farther north and west. These verified conditions, rather than earlier ensemble spreads, anchor trader consensus on market resolution.
